We now have the new COC Smart Chips™ for our HP 564, 920 cartridges. They are now installed on our Executive III Series Continuous Ink Supply Systems and refillable cartridges. Included in this new series is a new designed ink tank with an isobaric air chamber that will balance the proper air and ink supplied to the print head. We have also added our new double loop hose bracket™ and new style ink system cartridges.
